Opus Technologies - LD2.2
2 x 7A Dual Channel Induction Loop Amplifier
Product Description
The Opus Technologies LD2.2 is a cutting-edge, low-loss magnetic loop amplifier featuring dual, independent, out-of-phase amplifiers.
Delivering a powerful 2x7A rms output with Automatic Gain Control (AGC), it ensures optimal audio quality across various listening environments.
A sophisticated fault detection system continuously monitors both the amplifier and the loop, providing real-time status updates on the front panel and through a dry contact interface. This proactive approach enhances system reliability and facilitates troubleshooting.
Designed for flexibility, the OPUS LD2.2 can be installed in adjacent rooms, such as amphitheatres or courtrooms, using a hairpin loop configuration. This arrangement minimizes external magnetic field radiation, guaranteeing uniform audio coverage and reducing distortion caused by metal structures.
Built on a foundation of proven technology and meticulous manufacturing, the Opus Technologies LD2.2 is backed by a comprehensive 5-year warranty, demonstrating the company's commitment to quality and reliability.
